Mohamed ayed Posted June 8, 2022 Report Share Posted June 8, 2022 Hello there, I have AEM wideband Controller Connected to AEM CD7 Dash on a low speed Bus ( 500KBit/sec), I m trying to transmit the data from the Dash to the ECU on high speed Bus( 1KBit/sec) here is my setup and it only reads 1 on the ECU right now before using 1000 multiplier it used to read 0.001 I think the problem with the offset how the dash store the data ANY HELP.

Adamw Posted June 8, 2022 Report Share Posted June 8, 2022 You will need 16bits at both ends. Link G4+ will divide incoming lambda value by 1000, (to achieve 0.001 resolution) so you will need to multiply by 1000 before sending at the AEM end.

Mohamed ayed Posted June 8, 2022 Author Report Share Posted June 8, 2022 8 bit is the max length in the Dash software is this the problem i tried to multiply by 1000 at the dash and divide by 1000 at the ECU it Reads 0.00 Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 8, 2022 Report Share Posted June 8, 2022 8 bit is not enough, it would only allow a max of 0.255 lambda to be sent. Change Type to Unsigned Int16 BE Quote Link to comment Share on other sites More sharing options...
